[0002]

2. Description of the Related Art A wide variety of massage machines have been known as a massage machine in which a pair of massaging elements mounted on a backrest of a chair are swung and vertically moved.
In recent years, various improvements have been made to these massage machines in response to the demands of users, and the mechanism thereof has been significantly improved. For example, in the massage machine described in Japanese Examined Patent Publication No. 14057/1990, means for adjusting the interval between a pair of swinging massaging elements, means for adjusting the protrusion amount of the massaging elements, etc. are incorporated, and each part of the human body is incorporated. It is considered that each is given an appropriate massage.

[0003]

The massaging machine described in the above publication is constructed so that the interval between the treatment elements and the amount of protrusion can be adjusted, and the massaging apparatus can appropriately and effectively rub against each part of the human body. A massage can be given, but a shiatsu massage cannot be performed. Also,
A massager is also provided that is configured to be able to perform a striking motion in addition to a rocking and kneading motion on the treatment element. However, separate motors are used for conversion of the motion of the treatment element and movement of the treatment element. The fact is that while one motor is operating, the other motor is at rest, and the operating efficiency of the expensive motor is low and it is extremely uneconomical. The object of the present invention is 1
(EN) Provided is a massage machine having a simple structure in which two kinds of motions, that is, a swinging motion and a pushing motion of a treatment element, can be driven by one motor, and the distance between the treatment elements can be adjusted and the apparatus can be moved up and down.
